Coefficient Of Rolling Friction Rubber On Steel

Two forms of this are hysteresis losses see.

Coefficient of rolling friction rubber on steel. F f frictional force n lb. F f μ n 1. F r rolling resistance or rolling friction n lb f. By ron kurtus 20 november 2016 the coefficient of rolling friction is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling.

Static friction is friction between two or more solid objects that are not moving relative to each other. The frictional force can be expressed as. The friction force is the force exerted by a surface when an object moves across it or makes an effort to move across it. Coefficients of friction between materials are best determined through testing.

C rolling resistance coefficient dimensionless coefficient of rolling friction crf. Because of the various factors the coefficient of rolling friction is usually determined. The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The rolling resistance can be expressed as.

μ static μ s or kinetic μ k frictional coefficient. N normal force between the surfaces n lb there are at least two types of friction forces. Rolling resistance sometimes called rolling friction or rolling drag is the force resisting the motion when a body such as a ball tire or wheel rolls on a surface it is mainly caused by non elastic effects. That is not all the energy needed for deformation or movement of the wheel roadbed etc is recovered when the pressure is removed.

Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. Coefficient of rolling friction. F r c w 1. The value of μ s is generally higher than the value of μ k for a given combination of materials.

The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction.
